More than 1,300 homes could be built in Co Antrim along with a new motorway road link as plans progress with an ambitious scheme.
Developers have submitted a pre-application notice for the development of a new link road on the M1 motorway at Sprucefield, and the Knockmore Road junction, outside Lisburn.
The application has been made by developer Neptune Carleton.
A consultation is due to take place at the end of this month to gauge public opinion over the plans.
A letter from planning consultants Clyde Shanks says "public consultation information sessions" are due to take place at the Premier Inn on the Hillsborough Road on September 25 and 26.
If the plans, which could include 1,300 homes on the large site at Blaris, get the go-ahead, it would be one of the largest residential property developments to be built in Northern Ireland in recent years.
A spokeswoman for Lisburn and Castlereagh City Council said: "As with all planning applications, all proposed developments pertaining to the area are subject to satisfactory planning considerations.
"All planning applications for the area will be considered and decided on through the council's planning committee."
